BRUSH HEAD.

Application led February 9, 1924. Serial No. 691,708.

To all whom t may concern.'

Be it known that I, WILLIAM D. Rosie, a citizen of the United States of America, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Brush Heads, of which the following is a specification.

The invention relates to an improvement in brushes for general cleaning and the like, and particularly to a brush head, wherein the main section is constructed of rubber throughout, with formed edges which are adapted to be stretched or expanded over and snugly embrace and .interit with the bristle carrying portion of the head, to thereby snugly retain the sections of the head together.

.k further object of the invention is the provision of means whereby the handle receiving portion of the head may be disosed at varying points on the head or aterally otl'set from the head roper to thereby avoid undue obstruction 1n the use of the brush particularly in operating in narrow or restricted areas.

The invention is illustrated in the accompanying drawings, in which:

Fig. 1 is a plan of the improved brush head showing a separable offset handle socket.

Fig. 2 is a section on line 4 4 of Fig. 3.

Fig. 3 is a section on line 5-5 of Fig. 3.

Fig. 4 is a plan view of the bristle section.

Fig. 5 is a plan of another form of head in which the handle receiving portion is independent of but adapted to intert with the main securing section of the head.

Fig. 6 is a vertical section of the same.

Fig. 7 is a plan of another form of brush with the handle receiving portion independent of the main securing portion, with the handle receiving projection offset from the center of the brush.

Fig. 8 is a vertical section of the same.

In Figs. 1, 2, 3, and 4, the modified form of brush head is shown, wherein the clincher section 19 is formed as an annular band, having an inwardly projecting edge section 20 of reduced thickness, formed with a depending projection 21 to seat in a recess 22 1n the bristle section 23. The bristle section is formed with a diametrically arranged channel or recess 24, the projection 21 of the clincher being interrupted throughout the width of this channel. A handle member comprising a narrow 1netallic strip 25 is seated in the channel 24. and extends through a slot 26 in'the clincher section, being formed beyond the latter with a socket 27 to receive a handle. A tie plate 28 is arranged to overlie and rest upon the shouldered portion 2O of the clincher section, the whole being secured by bolts 29 passing through the tie plate, the handle plate 25, and the bristle section. Bolts 30 seated in recesses in the lower surface of the bristle section hold the bolts in position.

In this form, the brush head is substantially thin, has a marginal protector in the clincher section, and the handle portion is offset from the brush head proper to permit reaching into restricted spaces without interference.

Figs. 5 and 6, illustrate a slight modification in that the clincher section, here indicated at 26, is formed with an annular open- Y ing 27 in its upper surface, so that the clincher section is in effect an annular band, the depending edge 27 of which is adapted to engage and intert with an appropriately formed edge 28 of the bristle section 29. The annular edge of the opening in the upper portion of the clincher section is cut away to form a shoulder 30 and extended below said shoulder as an annular projection 31 to seat in a recess 32 in the bristle section. A handle carrying section 33 is arranged to lit within the annular opening of the clincher section. the edge of such annular carrying section being formed at 34 to engage the shoulder 30 of the clincher section and intertit therewith. Securing bolts 35 are provided for securing the handle carrying section directly to the bristle section 29. and by reason of the shoulder bearing of this handle carrying section 33, it will be seen that the clincher section is rigidly secured in place. The brush head has the handle receiving projection 39 located adjacent one edge of the section 33, so that the handle 40 seating in the recess 41 of such projection projects practically from one edge of the brush rather than from the central portion thereof.

In Figs. 7 and 8, the clincher section 42 having the usual clincher edges 43 to ernbrace the bristle section 44 is recessed on the upper edge t0 receive .e ,metal plate 45,

preferably of cross form, one arm of which is extended beyond the edge of the clincher section and appropriately formed to provide a socket 46 for the reception of a handle 47. Securing bolts t8 pass through the metal plate preferably adjacentthe terminals of the arms, through the clincher section, and take into the bristle section, thus rigidly connecting all parts.

It is to be understood that the clincher section is of rubber, sulliciently pliable to permit the edges to be stretched over the corresponding edges of the bristle section, so that the inherent elasticity of the clincher section will tightly grip the bristle section and hold the same. Through the use of the securing bolts,.the clincher section and bristle head are so united as to prevent the possibility of separation in use.

In the use of a brush head constructed as described, it is apparent that the entire surface of the brush head which is at all liable to come into contact with a surface or article in the use of the brush is ot sott rubber, and hence the possibility ot' marring such surface or article is correspondingly removed. Furthermore, by the use of a clinchcr section oit this type, the bristle section may be made of metal, hard rubber, or rai-ions other materials, and may be con* structed in a single piece as the clineher head when forced into position will securely hold the bristle section.

lvvhat l claim is:

l. ln combination With a brush head, a clincher member having an elastic marginal portion 'to engage the periphery of the brush head and be held thereon by its in- Lasalle hei-ent resiliency, the clincher member including a portion to bear upon the upper surface of the brush head, a handle receiving socket, and means adapted to engage the portion of the clincher member orerlying the back of said brush head and secured to said brush head for retaining the handle receiving socket on the brush head.

2. ln combination with a brush head, a clincher sectionhaving a resilient peripheral flange to be engaged over and rcsiliently retained ugon the edge of the brush head, a handle member bearing upon the brush head and underlying the clincher section, and means engaging the clincher section and the brush head to secure said clinclier section and handle member to the brush head.

3. ln combination with a brush head, of e clincher section haring an inherently resilient flange fitting over and resiliently engaging une edge oit the brush head, and a handle carrying strip p: sed through an opening in the clincher section and directl'ji engaging the brush head, said strip underlying the clin-cher section.

l. ln combi ation -with a brush head, ot a clincher section having an inherently resilient flange Fitting over and resilic-.ntlyv engaging the edge oit the brusi head, and a handle larrying strip n ed through an opening in the clincher section and directly engaging the brush head` said strip underlying the clincher section, and means to secure the clincher section, brush head, and. strip, together.

In testimony whereof l my signature.
